That is true.
I have seen many pilots have problems understanding how to fly the pitch/thrust tables in the 320. In some cases they want impossible things, like flying a given path (level, for instance) and pitch and thrust setting. You can't decide all of the terms of the equation!
I think it is due to the widespread reluctance to use thrust manually, so that when they see the table and they see a thrust setting on it, they want just to set that thrust and just forget thrust levers.
So they whole procedure becomes meaningless. The procedure states how it should be done, but I have never seen that issue properly discussed, and even some negative training regarding this procedure.
I was lucky because I was taught to fly according to that principle:
Attitude = Power + Performace
. So I have no problem with that. However I have the problem of coming to the conclusion that speed indications may be bull**** and then decide
if the safe conduct of the flight is impacted
or not (because it is nonsense, of course it is)
